Multiple modes (including a varying frequency disorienting strobe) help provide law enforcement with a tactical advantage in the field. Modes change via an integrated switch on each side of the handle. Runs on 6 CR123 batteries, which are located inside the handle. For use in: Corrections, SWAT, special operations (Military and Police), hostage rescue (search & recover), riot control and mobile security. NOTE: this integrated shield lighting and handle system requires holes through the shield, at specific distances. For this reason, it is NOT for aftermarket (retrofit) use. For retrofittable shield lights, check out our Discover Shield Single Switch and PRO III Shield Single Switch.
